STATES UNITE PATENT FRUIT-JAR.

SPECIFICATION forming-part of Letters Patent No. 312,596, dated February 1'7, 1885,

Application med May i5, 1594. (No mode.)

T0 tZZ whom, it may concern:

Beit known that I, JosErH BAREEOED WIL- sON, a citizen of the United States, residing at Clayton, in the county of Gloucester and State of New Jersey, have invented certain new and useful Improvements in Fruit-Jars; and I do hereby declare the following to be a sufficiently full, clear, and exact description thereof to enable others skilled in the art to make and use the said invention. i

This invention relates to fruit-j ars of glass or earthenware in which alimentary substances are preserved by excluding the atmosphere therefrom', and has for its obj ect the reduced cost of manufacture, greater cleanliness, convenience and facility ofopening and closing, and increased durability of the sealing bands or packings.`

The nature of this invention consists in providing upon a j ar-neck a series of circumferential ridges or bands and a similar series of ridges upon the stopper or cover, around which ridges a contractilole sealing-band is placed, impervious to air, which, by iitting closely on the series of ridges both on the jar and on the cover, prevents air from entering the jar, and by reason of being external to the jar avoids all contact of the sealingband with not only the contents of the jar, but also with any part of the surface of the jar over which the contents are poured in emptying the jar. It is preferable to have the neck and stopper of the jar of such form as to be self-centering; but the invention can be successfully used when this feature is omitted.

I will now proceed to particularly describe my invention, referring in so doing to the drawings annexed and the letters of reference marked thereon.

Figure l shows a vertical central section of a jar-neck and stopper containing my invention; Figs. 2, 3, and 4, the segregated parts thereof in section. Figs. o and 6 show modi` iications in form of the invention, also in section, the form ofthe body of the j ar not being involved in the invention', that portion is not drawn. Fig. 7 shows in section the means for closing and sealing the jars when india-rubber bands are not procurable.

The saine letters of reference apply to the same parts in the several figures.

A represents the jar-neck, provided with a series of annular ridges, B, which are preferably made narrow upon their periphery, but not so sharp as to cut caoutchouc or vulcanized india-rubber. C is the lid or stopper, also provided with a series of circumferential ridges, D.

As shown in Figs. l, 2, and 3, a portion of thestopper G nts into the neck A and centers it therein. In the form shown in Figs. 5, 6,and 7 the stopper nts over a portion of the neck of the jar, and thus centers it thereon.

Around the ridges B and D,wl1en the stoph Vthereon that the contraction of the band at the part embracing the joint of the neck and cover draws the cover firmly down on thejar-neck.

As shown in Fig. 6, instead of the indiarubber tube or band E, a cap or inverted cup, F, of the same material is used. This has the advantage of covering the stopper G, and making aneater finish, but is more expensive and not any more effectiveiu sealing.

The neck VA of the jar should be turned off evenly by grinding ou the edge, and the stopper Cso molded and handled in the annealing process as to fit snugly without rocking upon the neck A.

When the jars are heated and the stopper put on and the india-rubber tubes applied, the tubes E lit closely upon the ridges B and D, and as the jars cool, the elastic force of the air or vapor in the jar diminishes, and theatmospheric pressure forces the bands'E or caps F more firmly against the ridges B and D, in-

suring a fluidtight seal, and draws the cover firmly down upon the neck.

It is obvious from the. construction of the jar-neck and stopper that the contents of the jar do not come in contact with the part of the jar or stopper to which the sealing-band E is IOO applied, and the j ars are therefore more cleanly than those Where thev contents pour over the surfaces upon which sealing-gaskets are seated.

The tubes are easily made without Waste by cutting from rectangular sheets and closing the seam, and afterward dividing the tubes into proper lengths.

Vhen such jars are used in localities where vulcanized rubber fabrics are not procurable, they may be sealed by wrapping strong waxed paper or cloth or bladder, G, as shown in Fig. 7, around the ridges of the stopper and neck, and tying a cord tightly around the contiguous ridges B BandD D, and afterward between the lower ridge B ofthe neck and the upper ridge D ofthe stopper.

By rst tying the cord H over the waxed cloth, so as to bind it between the contiguous ridges B B ofthe neck and D D of the cover, the cloth is closed tightly and strained into close contact with the ridges, and when the cord J is afterward tied between the upper rings D and lower rings B it tightens the cover securely against the neck.

I am aware that jars have been made with a single rim upon the neck and a single rim upon the cover, which were embraced by a hand for the purpose of sealing thesame by an elastic band. -Such jars are objectionable in not holding the cover tightly against the neck, and are only susceptible of being closed by continuous bands of elastic material, and are hereby diselaimed, while the jars made as I have described effect such a hold upon the several rings on the lid and cover as to enable the contractible band to be stretched in the direction of the axis of the jar between the neck and cover, and by its reaction to rmly draw the cover down upon the jar-neck, and thus produce a more secure and reliable sealing, 4o and permit the use of such jars when elastic bands are not procurable.

Having described my invention, what I claim is- Y l. Afruit-jar provided with a series of circumferential ridges upon the neck, in combination with a cover provided with a similar series of ridges, and a contractible band surrounding said ridges and adapted by its `contraction as strained upon such ridges to draw the cover and jar toward each other, substantially as and for the purpose set forth.

2. Afruit-jar provided with a series of circumferential ridges upon the neck, in combination with a series of circumferential ridges upon the cover, both series of ridges being adapted to receive and effect a seal when surrounded by a contraetible band, substantially as set forth and described.
